A chatbot is only as good a teacher as the prompt you give it. These are the 15 prompts our team actually kept using after a month of practicing English with Claude and ChatGPT — copy them, paste them, and adjust the level to yours.
When we tested ChatGPT against dedicated AI tutor apps, one finding surprised us: the difference between a mediocre chatbot session and a great one was almost entirely the prompt. "Help me practice English" produces a polite, aimless chat. The prompts below produce something much closer to a real lesson — with corrections, difficulty control, and a reason to come back tomorrow.
Every prompt works in both Claude and ChatGPT (and most other capable chatbots). Replace the bracketed parts — [B1], [your topic] — with your own level and interests. If you don't know your CEFR level, prompt #2 will estimate it.
One honest caveat before you start. Chatbot prompts are brilliant for grammar, writing, and text conversation — but they won't hear your pronunciation or build a lesson plan around your recurring mistakes. For the speaking half of the job, our team's daily driver is Enverson AI, the speech-first tutor that won our 2026 AI language app ranking. The strongest routine we tested: app for speaking, prompts below for everything else.
| # | Category | Best for | Time per session |
|---|---|---|---|
| 1–3 | Conversation practice | Everyday fluency, thinking in English | 10–20 min |
| 4–6 | Grammar correction & explanation | Fixing recurring mistakes for good | 5–15 min |
| 7–9 | Vocabulary building | Learning words you'll actually use | 5–10 min |
| 10–12 | Writing feedback | Emails, essays, messages that sound natural | 10–15 min |
| 13–15 | Role-play & interviews | High-stakes situations, job prep | 15–20 min |
You are my English conversation partner. My level is [B1]. Let's have a natural conversation about [travel]. Reply in 2–4 sentences, then ask me a follow-up question. After each of my messages, add a short section called "Corrections" where you list my mistakes, the corrected version, and a one-line explanation of why. If I make no mistakes, suggest one more natural way to phrase what I said.
This single instruction — converse first, correct after — fixes the biggest failure mode of chatbot practice: conversations that flow but teach nothing, or corrections that kill the flow.
Ask me 8 questions one at a time, increasing in difficulty, to estimate my CEFR English level (A1–C2). Judge my grammar, vocabulary range, and complexity. After the last question, tell me my estimated level, my three biggest weaknesses, and what to practice first.
My English level is [B2]. Give me a mildly controversial statement about [technology] and argue for it. I will argue against it. Challenge my arguments and push me to justify my opinions. Correct only mistakes that a native speaker would notice, at the end of each of your replies.
Debate forces you out of memorized phrases faster than any polite small talk.
Explain the difference between [present perfect] and [past simple] as if I were a [B1] student whose native language is [Spanish]. Give 5 example pairs where choosing the wrong one changes the meaning, then quiz me with 5 fill-in-the-blank sentences one at a time and correct my answers.
Naming your native language matters — the bot will anticipate the exact transfer errors you're likely to make.
Here are sentences I wrote this week that felt wrong or difficult: [paste 5–10 sentences]. Correct each one, group my mistakes into patterns, and give me one rule per pattern to remember. Then create 5 practice sentences targeting my worst pattern.
I wrote: "[your sentence]". A more natural version is: "[the corrected version you were given]". Explain exactly why my version sounds wrong or unnatural, and whether it would ever be acceptable in some context.
Here is a paragraph I wrote: [paste it]. Keep my meaning but show me 5 places where a more precise or more natural word would improve it. For each, give the word, an example sentence, and one collocation it commonly appears in.
I have a [meeting about project deadlines] tomorrow in English. Give me the 15 most useful words and phrases for this exact situation, each with a short example. Then role-play the first two minutes of that situation with me.
Here are words I learned recently: [list 10 words]. Quiz me on them one at a time: first meaning, then ask me to use each in a sentence about my own life. Correct unnatural usage. Track my score and tell me which words to review again tomorrow.
Review this text I wrote in English: [paste text]. First pass: correct real errors (grammar, wrong words) with a one-line reason for each. Second pass: rewrite it the way an educated native speaker would, and list the 3 most useful differences between your version and mine.
Here is my email draft: [paste it]. Rewrite it in three versions: friendly-informal, professional, and very formal. Point out which phrases changed between versions so I learn what controls tone in English.
Act as an IELTS writing examiner. Give me a Task 2 question. I will write my answer here. Grade it with the official criteria, estimate my band score, and show me exactly which sentences cost me points and how to fix them.
You are a hiring manager interviewing me for a [marketing manager] position at an international company. Ask me realistic questions one at a time, including follow-ups that probe my answers. After every answer, give brief feedback on my English (errors + more natural phrasing) before the next question. Stay in character otherwise.
Role-play: you are an unhappy customer and I am the support agent. You have a [billing problem]. Be realistically difficult but not abusive. After we resolve it, break character and review my English: what I handled well, my mistakes, and 5 phrases that would have sounded more professional.
Simulate small talk with a colleague in the office kitchen. My level is [B1]. Keep your replies short and natural, use common idioms occasionally and explain them in brackets the first time. Gently correct me at the end of the conversation, not during it.
| Habit | Why it matters |
|---|---|
| Reuse the same 2–3 prompts daily instead of hunting for new ones | Routine beats novelty; the prompt is the curriculum |
| Keep a "mistake log" and feed it back weekly (prompt #5) | Chatbots don't remember your weaknesses across chats — you must |
| Say your answers out loud before typing them | Recovers some speaking practice from a text medium |
| Pair prompts with a speech-first app for real conversation | Apps like Enverson AI handle pronunciation, structure, and daily speaking reps automatically |
| End each session by asking for tomorrow's assignment | Removes the blank-box problem that kills consistency |
Claude and ChatGPT are the most patient English teachers who ever lived — but only if you tell them how to teach. The fifteen prompts above cover the full text-based loop: conversation, grammar, vocabulary, writing, and high-stakes role-play. What they can't cover is the spoken half of fluency, which is why our recommended 2026 stack is simple: these prompts for the desk work, and a dedicated speech-first tutor like Enverson AI for the daily conversation reps. If you're deciding between the two approaches, our ChatGPT vs. AI tutor apps test settles it in detail.
You can practice very effectively — grammar explanations, writing feedback, vocabulary building, and text conversation are all excellent. What chatbots don't provide is a structured course: no lesson path, no automatic weak-point tracking, and limited speech-first practice. Pair them with a dedicated speaking app such as Enverson AI for the full loop.
Both are excellent, and every prompt here works in either. In our use, Claude tends to give more thorough, patient corrections on longer texts, while ChatGPT's voice mode is convenient for casual spoken practice. Consistency matters far more than the choice of chatbot.
Tell the bot exactly how to behave: reply naturally first, then add a short "Corrections" section listing your mistakes and why they're wrong. That one instruction (see prompt #1) keeps the flow while preserving the feedback loop.
Consistency and speaking volume. A blank prompt box makes you decide what to practice every day, and text chat produces little actual speaking. Most learners do best combining these prompts with a speech-first AI tutor app like Enverson AI for daily conversation.
